Title: Data Processing Systems
Inventor: ARULPRAGASAM JEGANANDARAJ AMAL
IPC: G06F11/14
Filed: 1968-07-19
Abstract: 1,163,859. Data processing. INTERNATIONAL BUSINESS MACHINES CORP. 19 July, 1968, No. 34429/68. Heading G4A. In a data processing system, a recovery log unit maintains a profile of a first CPU (central processing unit) updated to a time before error is detected in the first CPU, and detection of error in the first CPU causes a second CPU to process the profile into storable form and store it in common main storage. The profile is all information necessary to permit a cleared CPU to continue its programme where it left off, including information of pending interrupts. Detection of error prevents further updating of the profile, and an error which persists despite instruction retry, or power failure, causes the second CPU to process the profile as stated above. The second CPU has its own recovery log unit and is normally concerned with its own tasks, and when required to process the profile of the other CPU as above, it temporarily stores its own working section in the main storage. The second CPU may take over the tasks of the first, using the profile of the first, in which case it processes its own profile and stores it in the main storage. The first CPU can perform for the second the services which the second is described above as performing for the first, and further CPU's can be provided. A profile can be forced into the system for diagnostic purposes.

Title: Hollow charge projectile
IPC: F42C1/06
Filed: 1953-12-11
Abstract: 734,920. Ammunition projectiles and fuzes therefor. ANSTALT FUR DIE ENTWICKLUNG VON ERFINDUNGEN UND GEWERBLICHEN ANWENDUNGEN ENERGA. Dec. 11, 1953 [Dec. 30, 1952], No. 34615/53. Class 9(1). A hollow charge projectile, Fig. 6, is provided with an impact and inertia operated fuze having a body 2 mounted in a fuze carrier 3, which is fixed in a tubular body 4. The assembly constitutes an antenna mounted in the ballistic cap 5, which is screwed into the body 9 of the projectile. The tube 4 extends within the cap to the base of a metal cone 10 lining the charge 7 and is aligned with a detonator 11 housed in a relay charge 8. Annular packings 12 hold the cone and hollow charge in position and also secure a conical element 13 centring the body 4. The body 4 may be made in sections screwed together and housing an explosive column preferably of compressed explosive, e.g. pen thrite, hexogen or derivatives thereof. Thin wads 14, 15, Fig. 7, are placed at the junction of the tube sections to prevent shifting of the elements during transport or on firing. Screwed into the rear section 4b of the body 4 is a detonating primer 16 having a concave base. The body 4 may be a single tube closed at the rear by a conical metal plug to produce a hollow-charge effect. In the fuze body 2 is mounted a striker carrier 19, Fig. 9, which also houses a primer 20 bearing against a cork ring 21. On impact, if the striker is not driven-in, the primer is thrown forwards due to inertia, compressing the ring 21 and impinging on the striker. The head of the striker is provided with a cutting edge 23, to bite into the target on impact, and a peripheral groove 26 receives the forward edge of the carrier 19, while the tip of the striker is centred by an internal flange 24. The primer 20 rests on a flexible washer 28 supported by a collar 29 which bears against the fuze carrier 3 and supports the fuze body 2 and striker carrier 19, the body 2 being crimped to the carrier 19 at the forward end. Behind the collar 29 is a safety chamber 30 decreasing in diameter and ending in a passage 32 below which is a second primer 33 directly above the explosive column 6. This second primer may be omitted. If the projectile is accidentally dropped on its head, the fuze body 2 is crushed and the collar 29 sheared, the fuze being driven into the safety chamber until halted by the narrowing of the chamber. Should the projectile fall accidentally on its base, the collar is again sheared by inertia and the fuze braked as before. When the projectile is fired, if the speed at impact is high the striker carrier 19 is crushed and the striker driven into the primer before shearing of the collar can occur. Otherwise the head 1 bites into the target, the collar shears and the fuze is driven into the chamber 30, the primer being carried by its momentum on to the striker. Fire is transmitted by the primer to the column 6 and through the cone 10 to the detonator 11 to explode the hollow charge.

Title: Improvements in or relating to wound dressings
IPC: A61L15/64
Filed: 1947-12-30
Abstract: A dressing for wounds involving loss of tissue, especially defects or cavities in hard tissues such as bones or teeth, comprises a body or solid substance to be fitted or packed into the defect or cavity in the wounded tissue to heal it, which body or substance is of a resorbable nature, devoid of animal protein in the native state and compatible with the tissue to be healed and is interwoven with pores or canals of ultracapillary nature which stimulate the ultracapillary system of the lost tissue, whereby the reticular stroma and blood plasma circulation interrupted in the wound surfaces may invade said pores or canals to promote healing.  According to the invention, dentine and dental enamel are living tissues nutrified by "ultracapillaries" emanating from the blood capillaries of the tooth pulp and the blood plasma circulation in the wound region is artificially restored by filling with a resorbable material forming a circulation system similar to that of the natural system of ultracapillaries, thus creating the physiological conditions for regeneration of tissue necessary for the healing of the wound concurrently with a resorption of the dressing.

Abstract: 891,918. Multiplex pulse code signalling. NIPPON ELECTRIC CO. Ltd. Oct. 14, 1960 [Oct. 19, 1959], No. 35319/60. Class 40(5).  In a time division multiplex pulse code modulation system in which one channel is used for a sequence of synchronizing pulses transmitted at the beginning of a frame, the received signals are supplied via a terminal 1 to the decoder 4, clock pulses being derived from the signal at 2 to operate the channel separation counter 3 to control the decoder 4. Synchronizing channel separation pulses from 3 are applied to AND gates 5 and 7, the AND gate 5 selecting a synchronizing pulse sequence from the received signals, and the AND gate 7 selecting clock pulses during the synchronizing channel time interval. The synchronizing pulse sequence is generated locally at 8 under the control of pulses from the gate 7 and is compared with the output of the gate 5 in the Exclusive OR circuit 6. If the two outputs are in time coincidence there is no output from the circuit 6, but if they are not in coincidence a pulse from the circuit 6 resets the channel separation counter 3 to the zero pulse position of the synchronizing code sequence, and resets the synchronizing code generator 8 to its zero position. Thereupon the comparison is resumed and repeated until synchronism is restored.
